11 Claims.

This invention relates'to the retail sale of eggs and the object is to provide a sack made inexpensively outof paper, with compartments just large enough to receive an egg positioned on end in each compartmentpreferably a dozen eggs k of'a full dozen.

I accomplish the above and other minor objects which will hereinafter appear by the means illustrated in the accompanying drawings, in which- Fig; '1 is a View in the fiat, or developed form of a sheet of paper, out and gummed for a long mouth'egg sack, ready for folding;

Fig. 21s a like View of a sheet of paper out and gummed for a short mouth egg sack;

- and Fig/12, a transverse vertical section on the line l2--l2 in Fig. 11. 7

Like characters indicate like parts in the several views of the drawings. Referring to Figs. 2, 8 and 9 the sheet is gummed at 8, 8 near both edges'and the gummed portions arefolded back double on the dotted lines9-9. with the gummed surfaces against the underside of the sheet. The sheet is then folded backon'the respective lines lll--| and lI-l I,

which brings their edges together on opposite sides of the lines l2--l2 and the gummed edges 8-8 are stuck to the main sheet adjacent the line l2l2 on the under side of the sheet in respect to Fig. 2, thereby doubling the paper as indicated in Fig. 8.

The paperthus doubled is next folded back transversely on the line |3--|3 and then in the opposite direction or forward on the respective lines l4-I4 and Iii-I5, as indicated in Fig. 9, into a, generally W-shape.

The sections between the line l2-l2 and the folds l0 and II on each side each have a pair of gummed strips [6, l7 and I8, I9 which are stuck V to the paper on the opposite side of fold l4--l4,

thereby holding the parts in contact with each other.

The strips between the fold lines 9 and I0, and 9 and II are slotted and punched in like manner so that a description of one will apply to both. The outer portions, that is the parts outside of the lines l4-l4 and I -45, have a pair of T-shaped slots and 2| with stems turned toward the fold lines and strips 22 and and 29and the respective lines l4 and I5 are slots 30 and 3| between which the gummed strips 26' are adhered when the sections are brought together by folding on lines l4 and I5.

Slots 33 in the form of a cross are made where the sides of the eggs will be contacted, to enable the paper to bulge there forming a holding seat but more particularly reducing the length of paper required to adequately house the eggs. This saving. of. paper while small for each egg sack, amounts to considerable in the aggregate and an object of my invention is so to reduce the cost of egg carriers that the added expense to the consumer will be negligible.

The gummed strips 22 and 23 adhere to the 5 sections on each side of slots 28 and 29 when folds are made on lines l4 and I5. The adhesion of strips 26 to the space between slots 39 and 3| holds the adjacent bottoms 40 together while the adjacent slots afford a resiliency that absorbs any impact due to normal or ordinary usage and save breakage.

The folded aspect of the bag is shown, partially opened or expanded, in Figs. 3 and 5 and filled in Figs. 4, 6 and '7. Obviously the sides may be pressed together into a compact article for storage and shipment.

As shown on larger scale in Figs. 10-12, the finished bag forms two types of cells-inner and outer end cells, each outer cell being formed to have the outer paper wall as the side walls and triangular flaps a, a, and b, b from the inner layer glued together along initially vertically extending lapped ends on each side of the slots 29. As indicated in Fig. 2, these slots 29 do not go entirely to the fold lines l4l4 and l5l5, and hence, a double thickness of paper c'is left vertically disposed, Fig. 12, to space the eggs from the base of the cells.

The inner cell retains the inner layer of paper for side walls, one end being defined by the transversely extending flaps a, b and b a, and the other end by the similar flaps d e and e (i joined in overlapping relation along the slots 28. In these inner cells, the transverse slots 24, 3| permit the inner layer of paper to spread out toward the outer layer, Figs. 10 and 11, and leave the vertical double thickness of paper ,1 to space the ends of the eggs from .the bottom fold lines M-l 4 and |5l5. Also, the additional slots 33, permit further expansion of these inner cell walls. The overlapping of the flaps a, b, c, and d along their slot lines 28 and 29, provides cushioning between eggs in adjacent cells.

The line l2-l2 is slotted at its midlength 42 and perforated for the remainder of the distances in order, thereby, to enable the package to be torn in two there when only a half dozen eggs are purchased. The separation is perfect by reason of the gummed strips 8--8 terminating at the line of separation; a V-shaped notch in the top edge of the sack starts the separation easily, and also enables the ends on one side of the top to be folded or telescoped into the ends of the other side in closing the package.

In the form shown in Figs. 1 and 10, the top of the sack is made long enough to permit folding over and over in the usual manner with sacks used for retail purchases, or to permit telescoping of the respective ends as in Fig. 10.

Gummed. spots. 45 may be deposited on the sack to stick the folded top members together,

, particularly in the short top sack.

. The paper is preferably slotted, gummed, and folded on a machine for that purpose in order to reduce the cost of manufacture.

Having thus fully described my invention what I claim as new and wish to secure by Letters Patent, is-

1. A paper sack formed out of a single sheet of paper folded double having individual egg compartments formed of the inner layer of the folded sheet, and having portions of opposite faces of the inner layer brought into contact and secured above a bottom fold of the outer layer of the folded sheet under the egg compartments.

. ,2. Inapaper sack for packaging eggs, a sheet of paper having opposing outer end portions folded back over the sheet on fold lines equally spaced from a longitudinal central line to bring the edges of those portions adjacent said central line; the sheet thus formed being folded back from the transverse center line; the back-turned top and bottom portions being folded back upwardly along transverse lines equally spaced' from the transverse central line; opposing vertical slots in both contacting faces of the inner layer of the paper extending from said central transverse line toward the spaced transverse lines; transverse slots across the upper ends of the vertical slots; and margins of the vertical slots being gummed to like margins of the opposing slots.

3. In a paper sack for packaging eggs, a sheet of paper having opposing outer end portions folded back over the sheet on fold lines equally spaced from a longitudinal central line to bring the edges of those portions adjacent said central line; the sheet thus formed being folded back from the transverse center line; the back-turned 'top and bottom portions being folded back upwardly along transverse lines equally spaced from the transverse central line; opposing vertical slots in both contacting faces of the inner layer of the paper extending from said. central transverse linc toward the spaced transverse lines; transverse slots across the upper ends of the vertical slots; and margins of the vertical slots being gummed to like margins of the opposing slots, and areas of said opposing faces being gummed together at the lower ends of the vertical slots.

4. In a paper sack for packaging eggs, a sheet of paper having opposing outer end portions folded back over the sheet on fold lines equally spaced from a longitudinal central line to bring the edges of those portions adjacent said central line; the sheet thus formed being folded back from the transverse center line; the back-turned top and bottomportions being folded back upwardly along transverse lines equally spaced from the transverse central line; opposing vertical slots in both contacting faces of the inner layer of the paper extending from said central transverse line toward the spaced transverse lines; transverse slots across the upper. ends of the vertical slots; and margins of the vertical slots being gummed to like margins of the opposing slots, and areas of said opposing faces being gummed together at the lower ends of the vertical slots; and slots in the said opposing faces between sets of said vertical slots.

5. An egg sack formed out of a double layer of paper, the inner layer being slotted on opposite sides above a fold line to form a plurality of flaps each having vertical and horizontal edges, the vertical edges of opposing flaps being pasted together forming plicates.

6. A paper egg sack formed out of a paper sheet folded double from each end and connected at the adjacent ends, the inner layer of the folded sheet being slotted toform a plurality of flaps each having vertical and horizontal edges, the vertical edges of opposing flaps being pasted together to form plicates.

7. An egg sack formed out of a sheet of paper folded double along a line spaced from each end, the inner layer of the folded sheet having T- shaped slots extending toward the fold line forming flaps with vertical edges, some of the edges of which are pasted together like edges of opposing slots forming plicates, said slots terminating above said fold line.

8. An egg sack formed out of two layers of paper folded to have an inwardly upwardly extending central fold, the inner layer of the folded sheet having T-shaped slots extending from said fold forming flaps with vertical edges, and outer portions of the two layers being folded back up along respective bottom fold lines, the outer portions carrying corresponding T slots, an edge of the one flap being pasted together with an edge of an opposite flap across the bottom folds to the outer walls of which are formed by the outer layer of the folded sheet;

9. An egg sack formed out of two layers of paper folded to have an inside upwardly extending fold between parallel bottom folds, the inner layer of the folded sheet having T-shaped slots extending from said upper fold forming flaps with vertical edges, like slots in the inner layer on the other sides above the bottom folds the edges of which slots are pasted together across the bottom folds forming plicates that make end walls of egg compartments the outer walls of which are formed by the outer layer of the folded sheet, a double pair of plicated compartments being separated by a pair of compartments the outer walls of which comprise both layers of the sheet.

10. An egg sack formed out of two layersof paper folded to have an inside upwardly extending fold between parallel bottom folds, the inner layer of the folded sheet having T-shaped slots extending from said upper fold forming flaps with vertical edges, like slots in the inner layer on the other sides above the bottom folds the edges of which slots are pasted together across the bottom folds forming plicates that make end walls of egg compartments the outer walls of which are formed by the outer layer of the folded sheet, a double pair of plicated compartments being separated by a pair of compartments the outer walls of which comprise both layers of the sheet, and transverse slots in the inner layer between the vertical slots.

11. An egg sack formed out of two layers of paper folded to have an inside upwardly extending fold between parallel bottom folds, the inner layer of the folded sheet having T-shaped slots extending from said upper fold forming flaps with vertical edges, like slots in the inner layer on the other sides above the bottom folds the edges of which slots are pasted together across the bottom folds forming plicates that make end walls of egg compartments the outer walls of which are formed by the outer layer of the folded sheet, a double pair of plioated compartments being separated by a pair of compartments the outer walls of which comprise both layers of the sheet, and transverse slots in the inner layer between the vertical slots, a transverse slot in each case being spaced above the bottom fold, and the inner layer of paper being pasted together below that transverse slot.
